I assume you are talking about a super thin crust pizza with a mixture of ground meat, tomatoes, and parsley on it. Turks and Armenians also eat this but call it "lahmajun".
Pizza Memo has three locations: College and Augusta, St. Clair and Dufferin, and Bloor and Bathurst. The St Clair location is the best, I've found.
They can also be found frozen at a number of Arabic/Middle Eastern stores. Arz Bakery is on Lawrence west of Victoria Park. Marche Istanbul is on Dufferin north of Lawrence.
If you are talking about something different than what I described, then it might help if you could describe what you are looking for.
